the hoover dam. why not while you're there. mitt romney was in colorado where he grabbed a burrito bowl at a local chipotle. he stopped to pose for pictures with this staff of the restaurant. love the guy on the right. amazing. presidential candidates spending most of their days in debate mode. it was up to the running mates to do the heavy lifting. joe biden was blasting the romney tax plan with being out of touch with the middle class. >> the romney/ryan tax plan will raise taxes on middle-class families with a child, one or more children by an additional $2,000 a year. how -- all kidding aside, without the boos. stop all that malarkey. this is deadly ernest, man. this is deadly ernest. how they can justify -- how they can justify raising taxes on the middle class that's been buried the last four years. how in lord's name can they justify it? >> the romney campaign picked up on that middle class being buried for the last four years during which president obama was in the white house while campaigning in iowa. paul ryan did not miss the opportunity to seize on biden's choice of words.
